What changes in the CSF would indicate neurosyphilis?
The diagnosis of neurosyphilis is based on a CSF WBC count of 20 cells/µL or greater, and/or a reactive CSF VDRL, and/or a positive CSF intrathecal T pallidum antibody index. CSF abnormalities include elevated protein levels and pleocytosis, which are found in up to 70% of patients.
Is neurosyphilis a meningitis?
Syphilitic meningitis is a form of neurosyphilis. This condition is a life-threatening complication of syphilis infection. Syphilis is a sexually transmitted infection.
What is CSF syphilis?
The CSF-VDRL test is done to diagnose syphilis in the brain or spinal cord. Brain and spinal cord involvement is often a sign of late-stage syphilis. Blood screening tests (VDRL and RPR) are better at detecting middle-stage (secondary) syphilis.
What are the serological tests to be performed on a CSF suspected of neurosyphilis?
Testing/serology The VDRL test and the rapid plasma reagin (RPR) test are nontreponemal tests, whereas FTA-ABS and microhemagglutination assay-T pallidum (MHA-TP) are treponemal tests.
How do you diagnose neurosyphilis?
Examination of CSF is the only way to diagnose asymptomatic neurosyphilis. A positive CSF VDRL is considered specific for neurosyphilis, but is not sensitive; CSF Venereal Disease Research Laboratory (VDRL) is positive in no more than about 50% of patients with symptomatic neurosyphilis.
What is the difference between syphilis and neurosyphilis?
Neurosyphilis is different from syphilis because it affects the nervous system, while syphilis is a sexually transmitted disease with different signs and symptoms. There are five types of neurosyphilis: asymptomatic neurosyphilis.
What part of the brain is affected by neurosyphilis?
Gummatous disease may also present with destructive inflammation and space-occupying lesions. It is caused by granulomatous destruction of visceral organs. They most often involve the frontal and parietal lobes of the brain. Movement disorders can be found in a small percentage of individuals with neurosyphilis.
How do you identify neurosyphilis?
Symptoms
- Abnormal walk (gait), or unable to walk.
- Numbness in the toes, feet, or legs.
- Problems with thinking, such as confusion or poor concentration.
- Mental problems, such as depression or irritability.
- Headache, seizures, or stiff neck.
- Loss of bladder control (incontinence)
- Tremors, or weakness.
Is neurosyphilis secondary or tertiary?
There are four stages of the disease: primary, secondary, latent, and tertiary (also known as neurosyphilis).

What is the pathophysiology of neurosyphilis?
Neurosyphilis is a manifestation of invasion of treponema pallidum spirochetes to the brain and dorsal column of spinal cord in tertiary syphilis. Only 25%–40% of persons who are not treated with penicillin will develop neurosyphilis.
What is neurosyphilis in the brain?
Neurosyphilis is a bacterial infection of the brain or spinal cord. It usually occurs in people who have had untreated syphilis for many years.
